E, orli iheaiia rALLs, YORK Be it known that I, C ARLEs Ia citizen of theiUnited States, residing at Niagara Falls, in the county of Niagara, State of New York, have invented certainnew and useful Improvements in; Abrasive- Wheel Trimmers; and I do hereby declare the following to be full, clear, andeiiact' description of the invention, such aswill enable others skilled in the art to which it appertains to make and use the same.

The present invention is directed to grind stone holders, and has for its object to so construct a device of this character thatydifferent sizes of abrasive wheels may be held while being shaved or trimmed prior to the burning operation. M q

A further object of the invention is to provide a device of this character. whichf s durable, exceedinglysimple in construction, cheap to manufacture, and one which will effectually hold a grind stone from'becoming displaced during the rotation of the holder. With these and other objects in view, this invention resides in the novel features of construction, formation, combination and arrangement of parts to-be hereinafter more fully described, claimed and. illustrated in the accompanying drawing, in which Figure l is a top plan view of the device,

showing the same adapted to receive an abrasive wheel of capacity size. Fig. 2 is a similar view, showing the holder adapted" to receive an abrasive wheel of lGSSSlZG.

Fig. 3 is a bottom planview of thedevice.

' Fig. 1 is a side elevationiof the device. Fig.

5 is a sectional view on line 55 of Fig. 1. Fig. 6 is a similar view on line6-6 of Fig. 2. Fig. 7 is a similar'view on line 7-7 of Fig. 2. Figl8is a sectional view through the device, showing the same adjusted for abrasivewheels comparatively thin.

Referring to the drawing, the numeral 1 designates a head, which may be rotated rapidly in any suitable manner, said head being circular in shape and is provided with I a plurality of sockets. 2 for detachable en- 7 I gagement by the posts 3 carried by the wheel supporting disk 4., the upper surface of grind-stone when placed thereon to more readily rotate with the disk 4. To hold the disk 4: spaced from the head 1, the same is provided with feet 6, which engage thehead so that the material scraped from the wheels between, said ring sections being held/in place by pegs 13, which detachably engage I plurality of f A RaslvEewHEEn TRIMMER f f Specificationof Letters i'atenti v fPat ntedN 3, 1914 7'formed inthe disk. 1

- fi lP 1 thr ughtheradiallyarr'anged slotsf l i Securedto' the periphery of diskt i band 8, the upper edge of which: rojects slightly" beyonfdfithe upper surface thereof so as to hold the sections 9 ofthe ring 10 in place so that when the disket, said ring will prevent dislodgment of the grindstone during the rotation a wheel is resting upon of the disk. 7

Theheight of thering l0 issuch that when a wheel is engaged upon the disk 4- one of the side faces thereof will beposi- J i tioned slightly above said ring, "and during the rotation of the disk a blade 11 isheld in contact with the face of the wheel, thus shavingor trimming thesame.

, When it is desired to trim wheels comparatively small,ring sectionsl2 are placed upon the-disk't and a wheel engagedthere the perforations l l formed in the "disk 4, said perforations being arranged ins alinement so that rings of different diameters may be interchangeably applied.

It is obvious that wheels of small diam :eter's are of less thickness, and toxfacilitate theshavlng of such wheels a supplemental disk 15 is employed, and is provided with a posts 16 which are designed to detachably engage the perforations 17 formedin the diske', said disk being also provided with radially arranged slots 18 so that the scraped material may bereadily brushed from the disk The disk15 is of such thickness that-when the, same rests upon the disk 4 the upper surface of a wheel will be above the plane of the "upper edges of the ring sections 12.

sleeves 19-are engaged upon the posts 16 so that the upper surface of the grindstone will be'properly positioned in respect to the ring sections 12, and as clearly shown in iFig.- 8 of the drawing.

From the foregoing description it willbe i seen that a holder-has been provided so constructed that wheels may be placed therein and properly shaved or scrapedupon' merely rapidly r0 applying a knife orblade to the tatingupper surfaces of the wheel.-

What is claimed is c 1 1. A holder of the class described, in com bination with a rotary'head of adisk de- 95 Should a wheel be comparatively thin, i

nectedto the first named-dislg as and for the purpose set forth.

A holder, in combination with a r0 tary head, of a disk detachably connected thereto, spaced rings mounted upon said disk and arranged one within the other, and

a supplemental disk detachably connected 7 to the first named disk and arranged in the innermost ring, and means for holding the supplemental disk in vertical adjusted positions in respect to the first named disk.

In testimony whereof, I affix my signature, in the presence of two witnesses.
